CAR-COUPLING.

Specification of Letters Patent.

Patented Sept. 16, 1913.

Application filed January 31, 1913. Serial No. 745,515.

.719 all whom it may concern:

Be it known that I, Josnrn Kovaos, a citizen of the United States, residing at Kulpmont, in the county of Northumberland and State of Pennsylvania, have invented a new and useful Car-Coupling, of which the following is a specification.

The present invention relates to improvements in car couplings, the primary object of the invention being the provision of a novel form of coupler in which the usual knuckle pin is dispensed with, and whereby the connecting medium is disposed for rotary and oscillatory movement within the coupling head to be projected and coactively engage a similar member of a mating coupling head, the operation in connecting and disconnecting of such member being manual and controlled by the brakeman or train assembling man.

A further objectof the present invention is the provision of a car coupling in which few parts are employed, and in which the coupling member and the means for operat ing the same are readily assembled in an integral or cast metal coupling and carrying member.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings Figure 1 is a top plan.

view of a car coupling with the connecting member in retracted position. Fig. 2 is a similar view with the connecting member in extended position. Fig. 3 is a horizontal sectional view through the coupling head with the connecting member in the position as shown in Fig. 2. Fig. 4 is a section taken on line H of Fig. 2. Fig. 5 is a perspective view of the oscillatory connecting mem ber perse.

Referring to the drawings, the numeral 1 designates the shank of the coupler, which has formed integral therewith, the coupling head 2, provided with the guiding lip 3 and with the segmental shaped receptacle 4 through the body thereof, there being provided a pillow or connection 5 for properly able and oscillatory coupling ring or member 6. This member 6 as clearly shown is provided with the head 7, which is disposed to assume the various positions, as clearly shown in Figs. 1 and 2 to engage a mating portion 7 of a coupler to retain the two coupling members in locked relation. The rear face of the connection 5 and the forward face of the receptacle or chamber 4 are disposed in the arcs of concentric circles and are extended across the draft line of the coupler.

Formed integral with the oscillatory member 6 upon the rear portion thereof, are the gear teeth 8, which are disposed to be in mesh at all times with the Worm gear 9 which is detachably keyed upon the operating shaft 11 and is insertible from below to be disposed upon said shaft through the vertical opening or socket 10 formed in the coupler head 2. This shaft 11 is held against displacement by means of the key 12 and is provided upon the opposite end with a shouldered end portion 13 for the reception of an operating handle. By this construction, the connection 5 is a means for holding the rack 8 engaged with the worm 9.

A lip 14 is formed integral with the coupling head 2 and is disposed to coact wit-h the oscillatory member 6 forming with the segmental opening or bore 1 of the coupling head 2, a guiding and reinforcing means for the coupling ring 6.

From the foregoing description, taken in connection with the drawings it is evident that the coupling ring or member 6 is mounted within the segmental bore 4 and so that the pulling strain thrown thereupon when the parts are in the position as shown in Figs. 2 and 3 is taken care of by the post 5 and also the projecting portion 14 of the coupling head 2, and that by the manipulation of the shaft 11, the worm 9 will impartthe desired oscillatory movement to the member 6 to move it to and from the posi= tions, as shown in Figs. 1 and 2.

WVhat is claimed is:

A coupler of the class described comprising a head having a chamber, the head being provided with a connection extended across the chamber, the rear face of the connection and the forward face of the chamber being disposed in the arcs of concentric circles and being extended, across the draft line; a segmental coupling member mounted to move in the chamber between said faces, the coupling member having a rack, one end of the In testimony that I claim the foregoing segmental member engaging the connection, as my own, I have hereto aflixed my signai0 in the drzltft Iineb, When the etherdend of the ture in the presence" of two Witnesses. segmenta mem er 1s in projecte position; 1 1

and a Worm in the head, with Which Worm JOSEFH EO e the rack meshes, the connection censtituting means for holding the rack engaged with the Worm.
